JOHN C. BAR-BER, 0 GI-IICAGO, ILLINOIS, ASSIGNOR TO STANDARD CAR TRUCK COMPANY, OF CHICAGO, ILLINOIS, A GORPGBATION OF NEW JERSEY.

ROLLER-BEARING DEVICE.

Application filed July 13, 1914.

To all 10 item it may concern:

Be it known that 1, JOHN G. BARBER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Roller-Bearing Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to lateral motion roller bearing devices, and more particularly, to that type of lateral motion bearing devices, wherein combined spring caps and roller bases are employed; and the invention has for its object to improve the construction of devices of the above noted character.

As an example of the illustrated use of a combined spring cap and roller base, the construction of which is improved by the present invention, my prior Patent 875,566, of date, December 31st, 1907, entitled Car truck, may be cited. In my said prior patent, the combined spring cap and roller base, therein marked by the numeral 9 and described as plates, are spring supported on the side frames of the truck, and are guided for vertical movements, but held against movements transversely of the truck, by large notches or column seats that embrace the truck columns.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings: Figure 1 is a plan view showing a combined spring cap and roller base constructed in accordance with my invention; Fig. 2 is a side elevation of the same; Fig. 3 is an end elevation thereof, with some parts broken away and with some parts sectioned; and Fig. 4 is a side elevation of the main body portion or plate of the said combined spring cap and roller base.

The plate or body section 1 is preferably a rolled or drop forged steel member having end flanges 2, and having on its upper surface, raised transverse portions formed with depressed self-centering roller seats 3, which latter, so far as the present invention is concerned, may be formed either on diverging straight or curved lines, or a combination of both straight and curved lines.

Serial No. 850,669.

In practice, the material for forming the round body sections or plates are rolled out in long bars and then cut into the proper lengths. To the end edges of the plates 1, separately formed castings, preferably of malleable iron, are rigidly secured, preferably by rivets. These east end pieces 4 are cast in the proper form to closely fit the upper surface of the end portion of the plate 1, and are provided with depending flanges that overlap the ends of the said plate. At their outer sides, the said end castings i are formed with large notches 5 that afford seats adapted to engage the truck columns, and to guide the combined spring cap and roller base for vertical movements. Between the roller bearing surfaces 3, the said end castings are provided with integral inwardly projecting roller stop lugs 6. As shown, each end casting l is rigidly secured to the plate 1, by a single rivet 7, but the number of rivets may, of course, be varied. The end castings 4, therefore, not only reinforce and strengthen the plate 1, but afford combined roller stops and column guides. The rollers, not shown, will of course, extend endwise on the roller seats 3 between the end castings l, so that the said end castings not only afford stops limiting the traveling movements of the rollers, but hold them against endwise displacement. With the above described construction, hard steel may be used for the roller seats while a relatively soft and tough material may be employed in the plate reinforcing end castings.

What I claim is:

1. A roller base comprising a plate having roller seats thereon, and independently formed end members rigidly secured to said plate and having projecting roller stops located between said roller seats.

2. A roller base comprising a plate having roller seats, and end castings rigidly secured to the ends of said plate and provided with roller stops located between said roller seats.

3. A roller base comprising a plate having roller seats, and end castings rigidly secured to the ends of said plate and provided with roller stops located between said roller seats, and formed with column engaging notches on their edges.

4. A roller base comprising a plate having raised transversely extended roller seats, of castings rigidly secured to the ends of said plate and provided with roller stops projecting over the end portions of said plate between the roller engaging seats thereof.

5. A combined spring cap and roller base comprising a steel plate having raised selfcentering roller seats, and end castings riveted to said plate and having roller stops projecting over the end portions of said plate between the raised roller seats thereof,
